Description

Technical Field

[0001] The utility model belongs to the technical field of road marking construction equipment, and particularly relates to an intelligent oil bath thermoplastic road marking sprayer. Background Art

[0002] A road marking machine is a machine used to draw road traffic safety signs, such as zebra crossings, sidewalks, lanes, parking spaces and other road signs. The hot-melt marking paint used by the road marking machine is in solid powder form at room temperature and usually needs to be melted into a fluid state in an oil bath before spraying. In addition, when spraying traffic signs, existing road marking machines require manual calibration of a preset track, and then workers move the road marking machine along the preset track. Or when spraying other complex graphics and landmark text, it is necessary to first make a corresponding hollow template according to the required logo and then spray. However, regardless of whether a preset track or a hollow template is used, when workers spray signs such as zebra crossings or parking spaces, they have to repeatedly move the road marking machine and adjust the spraying position because the line is not smooth and continuous. In addition, during the spraying process, debris or dust on the road will also affect the spraying effect.

[0003] To solve the above technical problems, a Chinese patent discloses a hot-melt road marking machine (patent announcement number: CN218027138U), which includes a vehicle body, a barrel, an air suction hood, a spray nozzle, an air blowing hood, and a filter box. When drawing road markings, workers need to push the handle to move the vehicle body, and clean the road surface by contacting the brush with the ground. The air pump can generate suction in the air suction hood to collect dust generated during cleaning. The liquid pump pumps the liquid in the barrel into the spray nozzle, and the spray nozzle coats the liquid on the road surface.

[0004] Although the above technical solution solves the problem that debris or dust on the road will affect the spraying of the road marking machine, when drawing some traffic signs that are not smooth and continuous routes (such as zebra crossings), workers need to move the road marking machine horizontally or diagonally to the starting end of the next line after drawing each line, and then continue to draw the next line. This reciprocating operation is time-consuming and labor-intensive. Utility Model Content

[0005] In view of this, the utility model discloses an intelligent oil bath thermoplastic road marking sprayer, which aims to solve the problem that the existing road marking machine needs to repeatedly move the marking machine and adjust the spraying position when drawing a pattern that is not smooth and continuous.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

DETAILED DESCRIPTION

[0021] like Figures 1-2 As shown,

[0022] An intelligent oil bath thermoplastic marking sprayer includes a frame 1 and a material storage barrel 2 and an air compressor 3 (a GZJB air compressor can be used) fixedly mounted on the frame 1; a stirring motor is fixedly mounted on the upper end of the material storage barrel 2; the output end of the stirring motor is vertically downward and is transmission-connected to a stirring shaft (not shown in the figure) located in the material storage barrel 2; a first drive motor located in the frame 1 is arranged on all four sides; the output end of the first drive motor is transmission-connected to a Mecanum wheel 4; the inlet end of the air compressor 3 is connected to the material storage barrel 2, and the output end of the air compressor 3 is connected to a nozzle 5; a first support block 6 for fixing the nozzle 5 is connected to a side surface of the frame 1; the nozzle 5 is fixedly arranged in the first support block 6, and the outlet end of the nozzle 5 is vertically facing the ground.

[0023] In this solution, a heating component is provided in the storage barrel 2 to heat and keep the material warm; an operating table for controlling the Mecanum wheels 4 and a seat for workers are also provided on the frame 1; by controlling the four Mecanum wheels 4 on the frame 1, omnidirectional movement can be achieved; when it is necessary to draw traffic safety signs on the road surface, the stirring motor and the air compressor 3 are started, and the stirring motor drives the stirring shaft in the storage barrel 2 to stir the material evenly; the air compressor 3 transports the material in the storage barrel 2 to the nozzle 5 and sprays it on the road; when the spraying is not continuous, the material in the storage barrel 2 is transported to the nozzle 5 and sprayed ... When marking consecutive traffic signs, such as zebra crossings, workers only need to control the operating console to move the frame 1 to the starting end of the first pattern and start drawing. After drawing is completed, the Mecanum wheels 4 are used to quickly and continuously move the frame 1 vertically or horizontally to the starting end of the next pattern (eliminating the need for traditional road marking machines to move back, turn, etc.), and cooperate with the opening and closing of the nozzle 5 to achieve rapid drawing of zebra crossings. Workers do not need to repeatedly move the road marking machine to adjust the spraying position, which saves time in adjusting the position of the road marking machine during spraying and improves the speed of spraying.

[0024] In this embodiment, the surface of the first support block 6 is provided with an adjustment component 7 for adjusting the position of the nozzle 5; the adjustment component 7 includes a second drive motor 701 (an 80ZFHA1 series servo motor can be used), a threaded rod 702 and two moving blocks 703; a groove is provided on the surface of the first support block 6 on the side close to the ground, the threaded rod 702 is arranged inside the groove and is arranged along the length direction of the first support block 6, and the two ends of the threaded rod 702 are rotatably connected to the first support block 6; the second drive motor 701 is fixed to the surface of the first support block 6, and the output end of the second drive motor 701 is connected to one end of the threaded rod 702 through a coupling; the two moving blocks 703 are both slidably arranged in the groove of the first support block 6; the surface of the threaded rod 702 is provided with threads with opposite rotation directions; the two moving blocks 703 are respectively threadedly connected to the threaded rod 702 with opposite rotation directions, and are symmetrically arranged about the threaded rod 702; the nozzle 5 is provided with two pieces and is respectively fixed on the surface of the moving block 703.

[0025] Since traffic safety signs come in many styles and are of different sizes and shapes, for example, although zebra crossings and solid lines on roads are similar, their widths are different. Therefore, when drawing, the distance between the nozzles 5 can be adjusted to draw patterns of different widths. In this solution, the threaded rod 702 is driven to rotate by the second drive motor 701, and the threaded rod 702 drives the two moving blocks 703 to move toward or away from each other, thereby adjusting the distance between the two nozzles 5, which can meet the drawing requirements of traffic safety signs of different widths, thereby improving the applicability of the device for drawing traffic safety signs.

[0026] In this embodiment, the front end of the frame 1 is also provided with a second support block 8 parallel to the first support block 6, and the surface of the second support block 8 is also provided with two of the nozzles 5 and the adjustment assembly 7 for adjusting the position of the nozzle 5; the nozzles 5 and the air compressor 3 are connected by pipes (the pipes between the surface of the frame 1 and the nozzles 5 use telescopic pipes); solenoid valves 11 are provided on the pipes; a main control module electrically connected to the solenoid valve 11 is provided in the frame 1, and the main control module is also electrically connected to the first drive motor and the second drive motor 701.

[0027] As shown in the figure, the output end of the air compressor 3 is connected to a diverter valve 12 to ensure that the flow rate of each nozzle 5 when spraying the material is the same. The diverter valve 12 has four outlets and is connected to the nozzle 5 through a pipe respectively; by controlling each solenoid valve 11, the channel between the corresponding nozzle 5 and the air compressor 3 can be opened or closed; when drawing a pattern or text, the pattern or text is imported into the main control module in a specific format such as DWG. The main control module automatically generates the drawing route of the pattern according to the imported text and automatically controls the movement of the corresponding mechanism; for example, a worker controls the Mecanum wheel 4 to move the frame 1 to the position where the pattern or text is drawn. At the starting end, a pattern is selected and drawing begins. The main control module controls the first drive motor, the second drive motor 701 and the corresponding solenoid valve 11 to cooperate with each other, so that when the frame 1 moves in one direction at a constant speed, the second drive motor 701 adjusts the position of the nozzle 5 in real time, and the corresponding nozzle 5 will intermittently spray material under the opening and closing of the solenoid valve 11, thereby realizing automatic drawing of patterns or texts; when a pattern is drawn, the main control module controls the first drive motor and the second drive motor 701 to stop running, and the solenoid valve 11 is closed; if you want to continue drawing the next pattern, repeat the above operation.

[0028] In this embodiment, a movable column 9 is provided on the side of the movable block 703 close to the ground, and the movable column 9 is threadedly connected to the movable block 703; the nozzle 5 is fixed to the side of the movable column 9 close to the ground.

[0029] By adjusting the height between the nozzle 5 and the ground, the range of the nozzle 5 spraying on the road surface can be fine-tuned, and the cooperation with the second drive motor 701 and the threaded rod 702 can further increase the spraying range of the nozzle 5, thereby improving the applicability of the device.

[0030] In this embodiment, the side surfaces of the first support block 6 and the second support block 8 are provided with a plurality of high-pressure nozzles 10 facing the ground; the high-pressure nozzles 10 are connected to an air pump (not shown in the figure) installed on the frame 1.

[0031] The air pump blows the compressed air toward the ground through the high-pressure nozzle 10, and the high-pressure nozzle 10 is set at an angle to clean the dust or debris on the ground in advance, thereby improving the firmness of the traffic signs when they are drawn.

[0032] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
